Designed for high-performance racing, the Tempest International is a sleek two-person keelboat that earned its place in sailing history as an Olympic class from 1972 to 1976. Created by Ian Proctor, the British designer renowned for producing responsive and technically demanding hulls, the Tempest combines the athleticism of dinghy sailing with the added stability of a fixed keel, making it a unique and exciting vessel to sail. Suited primarily to competitive racing on sheltered and coastal waters, the Tempest rewards skilled crews with its lively handling and sensitivity to sail trim and weight placement. Its narrow, planing hull is built for speed, and the boat is known for being physically demanding — particularly for the trapeze crew, who plays a critical role in managing heel and drive. This is not a boat for casual daysailing; it thrives in the hands of experienced sailors looking for a technical challenge. Though no longer an Olympic class, the Tempest retains a dedicated following and continues to be raced in class associations worldwide, offering a rewarding connection to a celebrated chapter of competitive sailing history.
